Once #![feature(or_patterns)] (#54883), i.e. pat_0 | ... | pat_n in nested positions, e.g. Some(Ok(a) | Err(b)) have progressed sufficiently in their implementation, e.g. when the MIR building implementation is done, we should extend the test suite for #![feature(bindings_after_at)] (#65490), e.g. b1 @ Some(b2), to exercise the combination of these two features. Ideally, we would also account for the combination of those two with #![feature(slice_patterns)] (#62254) and #![feature(box_patterns)] (#29641) as well to make things really air-tight.
